函数、方程、不等式有着紧密的联系,研究函数、方程时,一般都离不开不等式,比如解决函数的定义域、值域、单调性、最值等问题时,少了不等式真是“寸步难行”.特别是考查不等式中一元二次不等式和基本不等式这两个非常重要的知识点时,少数情况是单独考查它们,更多情况是在综合问题的解 Function, equation and inequality are closely related. When we study functions and equations, we can not do without inequality. For example, when we solve the problem of domain, monotonicity, value, etc., less inequality is really “ ”In particular, when examining two very important points of knowledge, such as the one-quadratic inequality and the basic inequality in inequality, the minority is to examine them individually, and more often the solution to the general problem
